Description

  The present invention relates to a game management system, and more particularly to a game management system that finds an illegal game based on game information.

  In recent years, a fraudulent act has been performed in which a special device is connected to a ball game machine (pachinko machine) to artificially manipulate the probability of jackpot in a variable display game. In such a fraudulent act, when the fraudulent himself plays a game with a ball game machine connected to the device, the probability of jackpot is set high, while a player other than the fraudulent acts as a game Can be set low. For this reason, the probability of jackpot hits falls within an average value when the ball game machine is viewed over a long period of time, despite illegal activities. Therefore, it is difficult to detect fraud by simply managing the overall frequency of jackpots.

  Therefore, a gaming machine monitoring apparatus has been proposed that determines the distribution of occurrence of jackpots and manages the presence or absence of fraud from the distribution state.

  For example, there is a gaming machine management device that judges whether the distribution is correct by testing the degree of fit between the theoretical distribution and the actual distribution (see, for example, Patent Document 1).

  In addition, a gaming machine that determines an abnormality of a gaming machine by comparing the actual number of games and the threshold value with the upper and lower limits of a region having a low occurrence frequency as threshold values from a theoretical frequency distribution or a frequency distribution obtained by simulation. There is a management device. Theoretical frequency distribution is calculated from the frequency distribution of the number of special prizes in a small number of rotations, extracting gaming machines that exceed the upper limit and the lower limit of the number of special prizes generated in a small number of rotations, or calculated from the frequency distribution of the number of occurrences of probability fluctuations For example, a gaming machine in which the occurrence frequency of jackpots due to the probability variation design is more than the theoretical value is extracted. In any case, it is a method to warn of the occurrence of fraud when a rare occurrence occurs from the frequency distribution of the number of games (special prizes, number of symbol stops, probability occurrence state, etc.) under the set conditions ( For example, see Patent Document 2.)

Both technologies are based on statistics, and the state of deviation from the theoretical distribution or the state where the frequency of occurrence is different compared to the value calculated from the distribution is abnormal. It is detected as a state.
JP-A-8-196722 Japanese Patent Laid-Open No. 11-342253

  In the abnormality determination based on the frequency distribution as described above, it is necessary to sufficiently accumulate data serving as a determination material. However, since a considerable amount of operating time is required to accumulate a sufficient amount of data, rapid abnormality detection cannot be performed.

  Therefore, in order to detect an abnormality quickly and in real time, it is necessary to loosen the criteria for abnormality determination. As a result, there are more cases where accidental accidental judgments are made up to gaming machines with frequent hits, for example, a risk factor of 5% is set at a game hall where hundreds of gaming machines are installed. In some cases, several tens of gaming machines are determined to be abnormal.

  In such a situation, it is difficult to arrange a game hall clerk every time an abnormality is detected to verify the abnormality of the gaming machine. As a result, an abnormality determination that exceeds the ability of the game hall, such as a situation in which an abnormality alarm is neglected, becomes an obstacle to the effective operation of the abnormality notification system.

  Accordingly, an object of the present invention is to provide a game management system that can effectively determine an abnormality in accordance with the situation of a game arcade.

Based on a comparison result between the determined value and a predetermined threshold value, an abnormality determination means for determining abnormality of the gaming machine, and based on information relating to the game collected from the gaming machine, the operating state of the gaming machine is determined. An operating state determining means for determining, an operating number detecting means for detecting the number of gaming machines determined to be operating by the operating state determining means among the gaming machines installed in the game hall, and the operating And a threshold value changing means for changing the threshold value based on the number of gaming machines in operation is detected by the detecting means.

  In the fourth invention, the threshold changing means changes to a strict threshold when the number of gaming machines detected by the operating number detecting means is small, and the number of gaming machines detected by the operating number detecting means is large. Should be changed to a sweet threshold.

  According to a fifth invention, in the fourth invention, there is provided a member registration means for registering a player as a member of a game hall, wherein the operation number detection means is a game machine determined to be in operation by the operation state determination means. Among them, the number of gaming machines registered as the member and playing a game satisfying a predetermined condition, and the number of gaming machines played by a player not registered as the member Are evaluated with different weights to detect the number of operating gaming machines.

  In the fifth aspect of the invention, the predetermined condition may be set with a player determined as a regular customer from the number of visits to the game hall and past game results. Further, it is preferable to determine the credibility of the registered contents declared by the player according to the delivery status of the direct mail sent from the game hall to the player, and set the determination result as a condition. For example, if there is a member who cannot deliver direct mail because the address is unknown, the content of the declaration of the member can be regarded as not credible. Treat it.

  The gaming microcomputer 401 is provided with an external communication terminal 404, and an identification number uniquely set in the gaming microcomputer 401 can be output from the external communication terminal 404. By connecting the inspection device or the game hall internal management device 1 to the terminal 404, the game hall internal management device 1 can identify the gaming machine 4a.

  In addition, the gaming microcomputer 401 outputs model specifying information related to the gaming machine 4 a to the game hall internal management device 1 via the board external information terminal 60.

  Further, the gaming microcomputer 401 outputs the variation display mode of the special symbol variation display game to the special symbol display 20A. Further, the special symbol winning memory number display is output to the special symbol memory display 20B.

  Further, the gaming microcomputer 401 outputs the variation display mode of the normal symbol variation display game to the ordinary symbol display 21A. Also, the normal symbol winning memory number display is output to the normal symbol memory display 21B.

  A special figure change start command, a change display command, an identification information command, a confirmation command, a demo display command, a fanfare command, a jackpot command, an error command, etc. are transmitted from the game control device 400 to the display control device 420 as a display control command signal. The Further, a command signal for changing the display mode according to a difference in the gaming state such as the normal gaming state, the special gaming state, the specific gaming state (probability variation state), or the variation time reduction state is also transmitted.

  The special figure change start command described above instructs the start of the change display game. The variation display command indicates a variation display mode of the identification information. The identification information command indicates identification information to be stopped and displayed as a result of the variable display game. The confirmation command instructs the stop of the variation display of the identification information. The demonstration display command instructs display performed when the variable display game is not played for a predetermined time. The fanfare command instructs display of the state before the transition to the special gaming state. The jackpot command instructs display during a special game state such as a round display during a special game state, an interval display, or a display between rounds during a special game state. The error command instructs display when there is an abnormality.

  The display control device 420 can grasp the transition of the game state managed by the game control device 400 based on these display control command signals (commands).

  The special symbols that are variably displayed by the control of the display control device 420 correspond to the special symbols that are variably displayed by the game control device 400, thereby providing a variety of display effects and enhancing the interest. Note that the special symbol may be variably displayed by the display control device 420.

  The discharge control device 410 controls the operation of the payout unit based on the prize ball command signal from the game control device 400 to discharge the prize ball. Further, based on the ball rental request signal from the ball rental unit 4b, the operation of the payout unit is controlled to discharge the ball rental.

  The variable display device 90 displays an image corresponding to the display area based on the image display signal from the display control device 420.

  The connection interface between the display control device 420 and the game control device 400 is provided with a buffer serving as a signal transmission direction restricting means, and communication between the game control device 400 and the display control device 420 is performed from the game control device 400. Only signal input to the display control device 420 is allowed, and signal output from the display control device 420 to the game control device 400 is prohibited. Thereby, it is possible to prevent an unauthorized signal from being input to the game control device 400 from the display control device 420. In the case where bidirectional communication is performed between the game control device 400 and the display control device 420, a bidirectional buffer can be used for the buffer circuit.

  The power supply device (not shown) of the gaming machine 4a includes a backup power supply unit and a power failure monitoring circuit in addition to the power supply circuit. When the power failure monitoring circuit detects a voltage drop of the power supply device, the power failure monitoring circuit sequentially outputs a power failure detection signal and a reset signal to the game control device 400 and the like.

  FIG. 6 is a timing diagram of game information output from the board external information 60 of the gaming machine 4a in the first embodiment of the present invention.

  The “special prize signal” is output during the special game state (big hit game). Based on the start time and end time of the output of the signal, the special prize signal can calculate the special prize time (time when the special game is executed) of the gaming machine 4a.

  The “probability change signal” is output during a special game state with a probability change symbol and during a specific game state (probability change state). The special game state based on the probability variation design means a state in which a big game that generates a probability fluctuation state occurs as a result of the variable display game and the special game (big game) is executed. That is, the three special symbols that are variably displayed on the screen of the variable display device 90 are generated by stopping at a special game combination (for example, odd numbers) of probability variation symbols.

  After the special game is executed and the special game state is ended, a probability variation state (a specific game state that favors the player with respect to the occurrence of the special game state) is generated in which the probability of occurrence of the special prize is higher than usual. During the probability fluctuation state, the normal symbol change display time is shorter than normal (for example, shortened from 30 seconds to 5 seconds), and when the normal symbol is a hit, the normal variable winning device opening time is normal. (For example, it is extended from 0.5 seconds to 3 seconds, or is repeatedly opened several times). Therefore, the probability of winning at the starting port is increased during the probability variation state than during the normal gaming state, and the number of special symbol winning memories can be increased as compared to during the normal gaming state.

  Note that the “special award signal” and the “probability change signal” are both signals indicating the gaming state, and thus are always output during the corresponding gaming state.

  The “start signal” is output at the time of starting the variable display game executed by winning a game ball at the start opening. Note that when a game ball wins the starting opening during the special game state, the number of winning balls is stored as a special symbol winning memory number, so that the variable display game is not immediately executed. Therefore, the start signal is not output during the special game state.

  Next, the output state of these signals during each gaming state will be described.

  First, a game ball is launched into the game area, and when a variable display game is started by winning a game ball at the start opening, a start signal is output. The start signal is output every time the variable display game starts during the normal gaming state. Note that the normal game state is a state in which no special game is executed. Until a special gaming state occurs as a result of the variable display game, the gaming machine 4a plays a game in the normal gaming state. In this state, neither the special prize signal nor the probability variation signal is output.

  When the result of the variable display game is a big hit, a special game is executed in the gaming machine 4a and a game is played in the special game state. At this time, if the result of the variation display game is a special game state with a probability variation symbol, both a special prize signal and a probability variation signal are output.

  Then, when the special game of the specified round is executed and the special game state is finished, the game machine 4a plays a game in a specific game state in which the occurrence probability of the special prize is higher than usual. In this state, the special prize signal is not output, but the probability variation signal is continuously output. Then, each time the game ball wins the starting opening, the variable display game is executed, and a start signal is output each time the variable display game is started.

  When the result of the variable display game in the specific game state is a big hit, the special game is executed in the gaming machine 4a and the special game is performed. At this time, if the result of the variable display game is a special game state with a normal symbol, the special prize signal is output, but the probability variation signal is not output.

  Then, when the special game of the specified round is executed and the special game state is ended, the game is performed in the normal game state in the gaming machine 4a. In this state, neither the special prize signal nor the probability variation signal is output. However, each time a game ball wins a starting opening, a variation display game is executed, and a start signal is output each time the variation display game is started.

  As described above, in the gaming machine 4a, when the launch of the game ball to the game area is started, the normal game state (a special game is not executed), the special game state (a special game is executed) Alternatively, a game is played in any state of the specific game state (probability variation state), and each signal is output from the gaming machine 4a according to the game state.

  FIG. 7 is a reference table setting process according to the first embodiment of this invention, and is executed by the CPU 101 of the game hall internal management device 1 and the application CPU 303 of the information collection terminal device 3.

  The reference table is a table commonly used for a plurality of models (models having different game performance (special prize occurrence probability)) in the calculation of the abnormality determination value (threshold value) for the gaming machine 4a. The reference table is generated by the CPU 101 of the game hall internal management device 1 (S11). The values in the reference table are calculated as follows.

  Let p be the probability of occurrence of a special prize for a predetermined gaming machine 4a. The special prize occurrence probability is a probability of occurrence of a special gaming state per one variation display game, and 0 <p <1. Usually, it is one tenth to several hundredths (for example, 1/315), and is predetermined for each gaming machine 4a.

  In the gaming machine 4a having a special prize occurrence probability of p, when n number of variable display games are tried, a special prize of an average λ (times) = n × p is obtained with n start numbers. This λ can be said to be the number of occurrences of a special prize expected with n start times, that is, an expected value.

In general, the prize occurrence probability p of the gaming machine 4a is one-tenth to one-hundredth, and since the value of p is extremely small, the value of n can be easily increased (for example, In the case of ball lending for 2,000 yen, the number of executions of the variable display game is about 50), and the Poisson distribution can be used as the probability that X special prizes will occur at the start number of n times. That is, the probability distribution (Poisson distribution) in which a special prize of X (times) occurs at the start number n (times) can be calculated by the following mathematical formula.
P (X) = e ^−λ λ ^X / X!

  Thus, by obtaining the distribution of the special prize occurrence probability as a Poisson distribution, the distribution can be easily calculated.

If application to the Poisson distribution is difficult, a binomial distribution may be used. The binomial distribution can be calculated by the following mathematical formula.
P (X) = _n C _x p ^x (1−p) ^nx

  Here, the Poisson probability P (X) is set to 1%. By setting the Poisson probability (risk rate) to 1%, it is possible to obtain a reference for determining an abnormal state that occurs only with a probability of 1%.

  Then, λ (reference value for abnormality determination) when X prizes are generated is calculated. In this case, two values of λ are calculated. One is λ in the case where it is determined that the X-time special prize is generated in an excessive state that occurs only at a rate of 1% or less. The value of λ is used when determining the special prize sparse state.

  Note that the special prize sparse state means a state in which an abnormal game that is a profit of the game hall is being performed because the special prize occurrence probability per the number of starts is extremely low. In this way, by detecting an abnormal gaming state that is beneficial to the game hall, a state in which a bona fide player is playing in a gaming machine that has been illegally operated by a malicious fraudster is detected. be able to.

  The other is λ in the case where it is determined that there are excessive states in which X prizes are generated only at a rate of 1% or less. The value of λ is used when determining the special prize dense state.

  It should be noted that the special prize dense state means a state in which the special prize occurrence probability per the number of starts is extremely high and an abnormal game (illegal act) that causes damage to the game hall is being performed. In this way, by detecting an abnormal gaming state that causes damage to the game hall, it is possible to detect a state in which a malicious fraudster is playing a game.

  The values shown in FIG. 8A are obtained by calculating such values of λ for X = 0 to 5, respectively.

  Similarly, FIG. 8B shows the value of λ when the Poisson probability is set to 5%. FIG. 8C shows the value of λ when the Poisson probability is set to 10%.

  The game hall internal management device 1 notifies the information collection terminal device 3 of the reference table generated in this way via the network communication port 106 (S12).

  The information collection terminal device 3 sets the reference table received from the game hall internal management device 1 in the RAM 305 (S13). Then, the information collection terminal device 3 calculates an abnormality determination value based on the set reference table (FIG. 9).

  It should be noted that an abnormality determination value is calculated by using a specific reference table (for example, a reference table with a risk rate of 1%, a risk rate of 5%, or a risk rate of 10% shown in FIGS. 8A to 8C) as standard. In this case, the reference table setting process is not performed every time the determination value is calculated, the specific reference table is recorded in the ROM 307 by default in the information collection terminal device 3, and the RAM 305 is activated when the information collection terminal device 3 is activated. May be set.

  Then, the generation of the reference table is performed only when an abnormality determination value is to be calculated using a non-standard reference table (for example, a reference table when the risk rate is 0.1% or the risk rate is 3%). Notification processing is performed (S11, S12). That is, the game hall internal management device 1 generates a non-standard reference table (S11), and notifies the information collection terminal device 3 of the generated reference table (S12). Then, the information collection terminal device 3 sets the reference table in the RAM 305 (S13).

  FIG. 9 is a flowchart of the game information collection process and the game information response process according to the first embodiment of the present invention, in which the game information collection process is executed by the CPU 101 of the game hall internal management device 1, and the information collection terminal device The game information response process is executed by the third application CPU 303.

  First, the game hall internal management device 1 polls the information collecting terminal device 3 at a predetermined timing (for example, every 5 minutes), and requests game information of each gaming machine 4a (S21).

  When the information collection terminal device 3 receives the request from the game hall internal management device 1, the information collection terminal device 3 displays the accumulated value of the game information collected from each gaming machine 4a connected to the information collection terminal device 3 through the network communication port 308. Through the game hall internal management device 1 (S22). And the game hall internal management apparatus 1 records the accumulated value of the notified game information in the RAM 103 (S23).

  In addition, the information collection terminal device 3 notifies the game hall internal management device 1 of the operation information of each gaming machine 4a together with the accumulated value of the game information (S24).

  The operation information is information indicating whether or not the gaming machine 4a is operating, and is determined based on the gaming information collected from the gaming machine 4a. When the information collection terminal device 3 notifies the accumulated value of the game information of the gaming machine 4a by polling from the game hall internal management device 1, the previous accumulated value of game information (for example, if the polling interval is every 5 minutes) If, for example, the game information notified 5 minutes ago) is compared with the accumulated value of the current game information, the game machine 4a can be determined to be operating. On the other hand, when the cumulative value of the previous game information is compared with the cumulative value of the current game information and there is no change in the game amount, it can be determined that the gaming machine 4a is not operating. Then, the information collection terminal device 3 notifies the game hall internal management device 1 as to whether the gaming machine 4a is operating as operating information.

  The game hall internal management device 1 records the operation information notified from the information collection terminal device 3, that is, whether or not the game machine 4a is operating in the RAM 103 (S25).

  Then, the game hall internal management device 1 determines whether or not the game information and the operation information regarding all the gaming machines 4a installed in the game hall have been collected (S26). When there is a gaming machine 4a from which these information has not been collected, the process returns to step S21 to continue the gaming information collection process.

  On the other hand, when the accumulated value of game information and operation information for all the gaming machines 4a are collected, the game hall internal management device 1 totals the accumulated value of game information for each island and the accumulated value of game information for the entire game hall. (S27). Specifically, the number of special prizes generated in the gaming machines 4a for each island or the entire game hall, the cumulative value of the number of starts, or the number of occurrences of a special gaming state during the execution of the variable display game a predetermined number of times That is, the special prize occurrence frequency is calculated.

  Next, the game hall internal management device 1 counts the operation information (S28). Specifically, based on the operation information notified from the information collection terminal device 3, the number of operating gaming machines 4a is calculated as the operation number. By counting the operation information, for example, the number of operations (for example, 250) is calculated by the sum of the operating gaming machines 4a, and the game is calculated by the sum of the operating gaming machines 4a and the gaming machines 4a that are not operating. The number of gaming machines in the entire field (for example, 400) is calculated.

  In this way, by calculating the number of operating game halls as a whole, based on the calculated value, the number of gaming machines 4a in which an abnormality is detected when the abnormality criterion is set to a predetermined value is estimated. be able to.

  Next, the game hall internal management device 1 performs the determination criterion setting process shown in FIG. 10 based on the calculated number of operations (S29). Then, the determination value calculated based on the set determination criterion is notified to the information collection terminal device 3 (S30, step S47 in FIG. 12).

  FIG. 10 shows determination criterion setting processing according to the first embodiment of this invention, which is executed by the CPU 101 of the game hall internal management device 1.

  First, the game hall internal management device 1 acquires the amount of monitoring resources for monitoring abnormalities of the gaming machine 4a managed by the labor management device 8 by receiving from the labor management device 8 (S31). The monitoring resource is a person who can monitor the illegal act in the gaming machine 4a on the floor of the game hall among the employees who work. In addition, you may use the monitoring camera 10 instead of an employee as a monitoring resource.

  The number of employees as the monitoring resource amount can be calculated based on the work status of the employees managed by the labor management apparatus 8. Specifically, the monitoring resource table shown in FIG. 11A is generated using the time recorder 9. This monitoring resource table is recorded in the RAM 103 of the labor management apparatus 8.

  The employee code in FIG. 11A is a number assigned to identify each employee. Job titles indicate the work each employee is responsible for. The work for managing the entire game hall is recorded as “management”, the work for general handling of gaming machines and players on the floor is “floor”, and the work for exchanging prizes and announcements in the hall is recorded as “counter”. Among these, the employee who can monitor the gaming machine 4a is an employee in charge of floor work. The status indicates the employee's attendance status. The employee whose attendance time is recorded is determined to be in a working state until the resigning time is recorded, and “attendance” is recorded in the status column. On the other hand, the employee whose work time is recorded is judged to be in the work leave state until the work time is recorded thereafter, and “working away” is recorded in the status column. The time is the time when each employee goes to work or leaves the office.

  When the labor management device 8 manages the entry / exit state of employees in the hall, the entry / exit state of each employee in the hall is recorded in the monitoring resource table of FIG. In this case, the employee whose entry time to the hall is recorded is determined to be in the entry state before the retreat time is recorded, and “entry” is recorded in the status column. On the other hand, the employee who has recorded the exit time from the hall is judged to be in an exit state until the entry time is recorded thereafter, and “exit” is recorded in the status column. In the time column, the time when each employee enters or leaves the room is recorded.

  The labor management device 8 can manage the number of employees in charge of management work, the number of employees in charge of floor work, and the number of employees in charge of counter work by using the monitoring resource table generated in this way. (FIG. 11B). Therefore, the game hall internal management device 1 acquires the number of employees in charge of floor work from the labor management device 8 as the monitoring resource amount.

  When the monitoring resource table records the entry / exit status of each employee into the hall, the labor management device 8 determines the number of employees in charge of floor work entering the hall and the floor work leaving the hall. You can manage the number of employees in charge. Then, the game hall internal management device 1 acquires the number of employees in charge of floor work entering the hall as the monitoring resource amount from the labor management device 8.

  Next, in step S <b> 32 of FIG. 10, the game hall internal management device 1 reads out and acquires the monitoring enhancement coefficient recorded in the RAM 103. The monitoring reinforcement coefficient is a load of abnormality monitoring that can be dealt with at a game hall, that is, a monitoring amount that one employee performs within a predetermined time (for example, the number of gaming machines 4a allocated to one employee, The number of times a single employee performs monitoring for a certain period of time), which is set using the setting input device 110 and recorded in the RAM 103. The monitoring enhancement coefficient is set to “strong” when the monitoring is strict and “weak” when the monitoring is lenient. When the monitoring reinforcement coefficient is “strong”, the number of gaming machines 4a determined to be abnormal (number of abnormality notifications) increases. When the monitoring reinforcement coefficient is “weak”, the number of gaming machines 4a determined to be abnormal ( The number of abnormal notifications) is reduced. The monitoring enhancement coefficient is set according to the game site monitoring policy. For example, in normal sales, it is set to “strong” that can be detected even if there is a minor abnormality, and the employee becomes busy compared to normal sales. In sales, it is set to “weak” in which no abnormality is detected when frequent special awards occur frequently. The monitoring enhancement coefficient is not limited to strong or weak, and may be set in multiple stages such as level 1 to level 5.

  Next, the game hall internal management device 1 calculates the amount of abnormality notification that can be verified, that is, the amount of monitoring that can be performed as a whole game hall (S33). The abnormality notification amount is determined in consideration of these factors based on the monitoring resource amount acquired in step S31 and the monitoring enhancement coefficient acquired in step S32. The abnormality notification amount increases as the monitoring resource amount increases, and decreases as the monitoring resource amount decreases. Further, the abnormality notification amount increases when the monitoring enhancement coefficient is “strong” and decreases when the monitoring enhancement coefficient is “weak”.

  Next, the game hall internal management device 1 acquires the operating number of the gaming machines 4a calculated by counting the operating information in step S28 of FIG. 9 (S34). Based on the number of operations and the abnormality notification amount calculated in step S33, an appropriate determination criterion for abnormality determination is calculated (S35). The determination standard becomes sweeter as the number of operations increases, and becomes stricter as the number of operations decreases.

  The game hall internal management device 1 sets the abnormality determination criterion thus calculated in the RAM 103 (S36). Then, after that, in step S30 in FIG. 9, the set abnormality determination criterion is notified to the information collection terminal device 3.

  FIG. 12 is a flowchart of the determination information setting process and the model identification information response process according to the first embodiment of this invention. The determination information is determined by the CPU 101 of the game hall internal management device 1 and the application CPU 303 of the information collection terminal device 3. The setting process is executed, and the model specifying information response process is executed by the gaming microcomputer 401 of the gaming machine 4a.

  First, the game hall internal management device 1 sets a criterion for determining an abnormality (S41). Specifically, the abnormality determination criterion calculated by the determination criterion setting process shown in FIG. 10 is set in the RAM 103 using the setting input device 110. Here, the criterion for when the monitoring enhancement coefficient is “weak” is set to 1% of the risk rate in both the special prize sparse state and the special prize dense state (FIG. 13A). Further, the determination criterion when the monitoring reinforcement coefficient is “strong” is set to a risk rate of 5% in both the special prize sparse state and the special prize dense state (FIG. 13C). Compared to the case where the monitoring reinforcement factor is “weak”, by setting a larger value of λ, which is the criterion for the case where the monitoring enhancement factor is “strong”, the abnormality judgment when the monitoring enhancement factor is “strong” The value (threshold value) becomes a strict standard, and the number of gaming machines 4a determined to be abnormal (the number of abnormality notifications) increases. Note that the numerical value of the determination criterion to be set is not limited to these values.

  Further, together with the determination criterion, the number of determinations of occurrence of a special prize that becomes an abnormality determination value is set (FIG. 13A). Here, in both cases where the monitoring enhancement coefficient is “weak” and “strong”, the special sparse state determination count is set to zero. Also, in both cases where the monitoring enhancement coefficient is “weak” and “strong”, the number of determinations of the special prize dense state is set to 3 times. However, the number of determinations to be set is not limited to these values.

  The determination criterion may be set to a different value for each model of the gaming machine 4a. These criteria are used to determine at what point an abnormality is detected, and to what extent damage can be tolerated when an abnormality occurs, based on the amusement park sales policy, the ability to respond to abnormality detection, and the degree of monitoring enhancement. Decided in consideration.

  Next, the game hall internal management device 1 requests the information collection terminal device 3 for model specifying information of the gaming machine 4a connected to the information collection terminal device 3 (S42). The information collection terminal device 3 starts the determination information setting process by receiving the request from the game hall internal management device 1.

  First, the information collection terminal device 3 requests model specifying information from the connected gaming machine 4a (S43). The gaming machine 4a connected to the information collecting terminal device 3 receives the request from the information collecting terminal device 3 and thereby starts the model specifying information response process.

  The gaming machine 4a notifies the information collecting terminal device 3 of the model specifying information of the gaming machine 4a (for example, the chip ID of the gaming machine 4a or the manufacturer code and the model code) via the external communication terminal 404 ( S44). Then, the information collection terminal device 3 notifies the game hall internal management device 1 of the model specifying information notified from the gaming machine 4a via the network communication port 308 (S45).

  When the game hall internal management device 1 receives the model specifying information of the gaming machine 4a from the information collecting terminal device 3, the gaming hall internal management device 1 specifies the model of the gaming machine 4a based on the model specifying information. And the probability information (special prize occurrence probability p) of the gaming machine 4a is specified by searching the model from the model information stored in the HDD 105 of the game hall internal management device 1 (S46).

  The model of the gaming machine 4a is specified by authenticating the uniquely set chip ID (unique information) included in the gaming microcomputer 401 of the gaming machine 4a with the model information stored in the game hall internal management device 1. be able to. Further, the game machine 4a transmits the manufacturer code and the model code stored in the game ROM (not shown) of the game machine 4a to the game hall internal management device 1, thereby specifying the model of the game machine 4a. it can. Based on the manufacturer code and the model code, the model name and the machine type can be specified. Specifically, if it is a pachinko machine, a pachislot machine, a game ball type, a medal type, or a pachinko machine, one type, two types, three types, if it is a pachislot machine, type A, type B, etc. Can be specified, whether it is a cash machine or a card machine. Note that the chip ID may be configured such that the model code is included in the chip ID. Thereby, the model code can be specified from the chip ID.

  In addition, instead of searching for model information stored in the HDD 105 of the game hall internal management device 1, the game machine performance (special prize occurrence probability p) is sent to an external organization such as a manufacturer of the game machine 4a via a communication line such as the Internet. You may make it inquire. Alternatively, the game hall internal management device 1 may directly set the prize occurrence probability p of the gaming machine 4a in the information collecting terminal device 3 without requesting the model identification information to the gaming machine 4a.

  Next, the game hall internal management device 1 notifies the information collection terminal device 3 of the determination criteria (risk rate, number of occurrences of special prize) for abnormality determination set in step S41 (S47). Further, the game hall internal management device 1 notifies the information collecting terminal device 3 of the special prize occurrence probability p of the gaming machine 4a identified in step S46 (S48).

  When the information collection terminal device 3 is notified of the determination criteria (risk rate, number of determinations of occurrence of special prize) and the special occurrence probability p of the gaming machine 4a from the game hall internal management device 1, the information collection terminal device 3 receives these information. The data is stored in the RAM 305 (S49, S50). When a plurality of gaming machines 4a are connected to one information collecting terminal device 3, the information collecting terminal device 3 sets these pieces of information in association with each gaming machine 4a.

  The determination criteria (risk rate, number of occurrences of special award) for abnormality determination set in FIGS. 13A and 13C are given in the determination value table (FIGS. 13B and 13D). It is set as an abnormality determination value for detecting a sparse state or a special prize dense state (S51).

  Since the judgment value table is a value reflecting information for each model such as the special prize occurrence probability p determined for each model of each gaming machine 4a, there is a different table for each gaming machine 4a if the gaming performance is different. Generated.

  Further, the special prize occurrence probability p of the set gaming machine 4a is used to calculate an abnormality determination value (starting number of the variable display game) that is a monitoring target period for detecting the special prize sparse state or the special prize dense state. . The abnormality determination value is calculated by the application CPU 303 of the information collection terminal device 3 by the following method.

  First, in calculating the abnormality determination value of the special prize sparse state when the monitoring reinforcement coefficient is “weak”, the determination criterion is set to 1% in FIG. Use the value. Among the special shortage determination values shown in FIG. 8A, the value of λ corresponding to “0” set as the number of special occurrence occurrence determinations in FIG. 13A is 4.61. Here, since λ = n × p, an abnormality determination value that becomes a monitoring target period can be obtained by multiplying the obtained λ by 1 / p. Here, 1453 (times) is obtained as the monitoring target period when p = 1/315 (FIG. 13B). In other words, the state where the special prize of 0 (judgment value) is generated at the start number of 1453 times (monitoring target period) is an excessive state that occurs only at a rate of 1%, and the monitoring enhancement coefficient is “weak” It can be determined that the special prize sparse state.

  When calculating the abnormality determination value of the special prize dense state when the monitoring reinforcement coefficient is “weak”, the determination criterion is set to 1% in FIG. 13A. Therefore, the excessive special determination value shown in FIG. Use. Of the over-specialty determination value shown in FIG. 8A, the value of λ corresponding to “3” set as the number of determinations for generation of the special prize in FIG. 13A is 0.43. Therefore, from λ = n × p, 136 (times) is obtained as the monitoring target period when p = 1/315 (FIG. 13B). In other words, the state where the special prize of 3 times (judgment value) occurs at the start number of 136 times (monitoring target period) is an excessive state that occurs only at a rate of 1%, and the monitoring enhancement coefficient is “weak”. It can be judged that the special prize is dense.

  Similarly, in the calculation of the abnormality determination value of the special prize sparse state and the special prize dense state when the monitoring enhancement coefficient is “strong”, the determination criterion is set to 5% in FIG. The value shown in (B) is used. Since the value of λ in the special prize underdetermination corresponding to the special prize sparse state is 3.00, 945 (times) is obtained as the monitoring target period when p = 1/315 (FIG. 13D). In addition, since the value of λ for the over-specialty determination corresponding to the special-dense state is 0.81, 256 (times) is obtained as the monitoring target period when p = 1/315 (FIG. 13D). In other words, a state where a special prize of 0 times (judgment value) is generated at a start number of 945 times (monitoring target period) is an excessive state that occurs only at a rate of 5%, and the monitoring enhancement coefficient is “strong”. It can be determined that the special prize sparse state. In addition, the state where the special prize of 3 times (judgment value) is generated at the start number of 256 times (monitoring target period) is an excessive state that occurs only at a rate of 5%, and the monitoring enhancement coefficient is “strong”. It can be judged that the special prize is dense.

  The value calculated in this way is set as an abnormality determination value serving as a monitoring target period for detecting the special prize sparse state or the special prize dense state in the determination value table (FIGS. 13B and 13D). (S51).

  In this way, the information collecting terminal device 3 can easily determine by simply giving the prize occurrence probability p of each gaming machine 4a as a parameter to a reference table (FIGS. 8A to 8C) preset in the RAM 305. A value table (FIG. 13B and FIG. 13D) can be generated. Therefore, when there is a model change of the gaming machine 4a, a troublesome setting operation accompanying the replacement of the gaming machine 4a is not required, so that it is possible to flexibly deal with frequent model changes due to frequent replacement of the gaming machines.

  Further, by storing a reference table in the information collection terminal device 3 and generating a determination value table in the information collection terminal device 3, the burden on the game hall internal management device 1 and the network is reduced, and abnormality is determined in real time. it can.

  FIG. 14 is a flowchart of the special sparse state monitoring process, the special sparse state acceptance process, and the special sparse state release acceptance process according to the first embodiment of this invention. The special prize is received by the CPU 101 of the game hall internal management device 1. The sparse state acceptance process and the special prize sparse state release acceptance process are executed, and the special sparse state monitoring process is executed by the application CPU 303 of the information collection terminal device 3.

  When the game is started by the player, the information collection terminal device 3 determines whether or not the special sparse state of the gaming machine 4a is detected by the special sparse state detection process shown in FIG. 15 (S61). When the special prize sparse state is detected based on the set determination value, the information collecting terminal device 3 informs the game hall internal management device 1 via the network communication port 308 that the corresponding gaming machine 4a is in the special sparse state. Notification is made (S62).

  When the game hall internal management device 1 receives the special sparse state notification of the gaming machine 4a from the information collecting terminal device 3 via the network communication port 106, it performs a special sparse state acceptance process (S63, S64). Specifically, a special sparse state flag is set in the gaming machine 4a that has been notified of the special sparse state (S63). Then, the output device 109 notifies that the gaming machine 4a is engaged in a suspicion that there is a suspicion for the game arcade (S64). As a notification method, an abnormality of the target gaming machine 4a is displayed on a display provided as the output device 109, or notified by a speaker. Further, the detected abnormality may be stored as a history in the HDD 105 of the game hall management device 1.

  On the other hand, if the special sparse state is not detected in step S61, the game hall internal management device 1 is not notified (S62), and the process proceeds to step S65.

  In step S65, when the special sparse state is released, the game hall internal management device 1 is notified via the network communication port 308.

  When the game hall internal management device 1 receives the special sparse state flag release notification of the gaming machine 4a from the information collecting terminal device 3 via the network communication port 106, the game sparse state release acceptance process (S66, S67) is performed. Do. Specifically, the special sparse state flag of the gaming machine 4a that has been notified to release the special sparse state flag is released (S66). Then, during the setting of the special prize sparse state flag, the alarm that has been notified by the output device 109 is canceled (S67).

  FIG. 15 is a flowchart illustrating special sparse state detection processing according to the first embodiment of this invention. The special sparse state detection process is executed by the application CPU 303 of the information collection terminal device 3 every time a start signal is detected from the gaming machine 4a.

  First, the information collecting terminal device 3 determines whether or not a start signal for a variable display game is detected from the gaming machine 4a (S71). When the start signal is not detected from the gaming machine 4a, the special sparse state detection process is terminated.

  On the other hand, when a start signal is detected from the gaming machine 4a, it is determined whether or not the gaming machine 4a is in a probability variation state depending on whether or not a probability variation signal is output from the gaming machine 4a (S72). When the gaming machine 4a is not in the probability variation state, a deviation value “0” is written in one storage area of the game history storage area shown in FIG. 16 (S74).

  When the gaming machine 4a is in the probability variation state, first, the probability variable multiple of the game machine 4a is added to the probability variable multiple carryover (S73). The probability variable multiple is a value obtained by dividing the special prize occurrence probability in the probability variation state by the special occurrence probability in the normal gaming state, and is an integer (for example, 5 (times)) or a decimal number (for example, 5.3 (times)). ).

The probability variable multiple carryover is a fraction of the probability variable multiple of the gaming machine 4a and is stored in the RAM 305. Specifically, in the probability variable multiple carryover, a fraction (decimal part) obtained by subtracting the integer part of the cumulative total of the probability variable multiples written up to the occurrence of the previous probability variation state is stored. Then, when a probability variable multiple is newly added in step S73, a value after addition represented by an integer or a decimal is stored. For example, when 0.8 is initially stored in the probability variable multiple carryover and the probability variable multiple added in step S73 is 5.3, 6.1 is stored in the probability variable multiple carryover after the addition. .

  Next, the information collection terminal device 3 writes the outlier “0” in the number of storage areas corresponding to the integer part of the values stored in the probability variable multiple carryover in the game history storage area shown in FIG. S75). That is, when the value stored in the probability variable multiple carryover is 6.1, the information collection terminal device 3 writes the deviation value “0” in the six storage areas of the game history storage area.

  Then, the probability variable multiple carryover is updated to a fraction (decimal part) obtained by subtracting the integer part of the cumulative number of the probability variable multiple (S76). That is, when the value stored in the probability variable multiple carryover is 6.1, 0.1 obtained by subtracting the integer part 6 is newly stored.

  In this way, by distinguishing between the case where the gaming machine 4a is in the normal gaming state and the case of the probability variation state, the deviation value “0” is written in the game history storage area, so that in the special sparse state detection processing, It is possible to eliminate the influence caused by the increase in the special prize occurrence probability. In addition, the abnormality determination process can be easily implemented because the normal gaming state and the probability variation state having different special occurrence probabilities can be handled in a unified manner without distinguishing the determination criteria for abnormality determination. Furthermore, since the abnormality determination is performed collectively without separating these states, information necessary for the determination is gathered quickly, and rapid abnormality detection can be performed. Further, by correcting the area where the game history is recorded by the probability variable multiple carryover, it is possible to prevent an error from accumulating in the number of executions of the variable display game during the monitoring period when the probability variable multiple is not an integer. . As a result, erroneous abnormality determination due to error accumulation can be prevented.

  Next, whether or not the gaming machine 4a is in the special gaming state is determined based on whether or not a special prize signal is output from the gaming machine 4a as a result of the variable display game corresponding to the start signal detected in step S71 (S77). ). When the gaming machine 4a is not in the special gaming state, the process proceeds to step S79.

  On the other hand, when the gaming machine 4a is in the special gaming state, it indicates that the result of the variable display game executed on the gaming machine 4a is a win, so that it has not been written in the gaming history storage area in step S74 or step S75. The hit value “1” is overwritten on the value “0” (S78).

  However, in step S75, since the shift value “0” is written in the number of storage areas corresponding to the integer part of the value stored in the probability variable multiple carryover of the game history storage area, among the plurality of storage areas, Only one storage area with the largest address is overwritten with the hit value “1”. As a result, the number of occurrences of the special prize can be accurately counted while eliminating the influence due to the increase in the special prize occurrence probability during the probability fluctuation state.

  Next, the special sparse state storage area (the number of areas corresponding to the monitoring target period of the special sparse state set in the determination value table of FIG. 13B or FIG. 13D with reference to the pointer in FIG. 16) The number of hit values “1” written in () is counted (S79). Then, a preliminarily calculated determination value of the special prize sparse state (FIG. 13B or FIG. 13D) is read (S80), and the total of the winning value “1” (number of special prize occurrences) is compared with the determination value. (S81). When the number of occurrences of the special prize is equal to or less than the determination value, the special prize occurrence frequency is too low, and the gaming machine 4a can be determined to be in the special prize sparse state, and thus the special prize sparse state flag is set in the gaming machine 4a ( S82).

  On the other hand, when the number of occurrences of the special prize is larger than the determination value, it is determined that the gaming machine 4a is not in the special prize sparse state. If the special sparse state flag is already set for the gaming machine 4a, the special sparse state flag is canceled.

  Instead of the start signal, a symbol confirmation signal (a signal indicating that the variation display game has been completed when the result mode of the variation display game is confirmed) may be used. In this case, the presence / absence of the special prize signal is determined after a predetermined time has elapsed since the symbol determination signal was detected.

  Thus, the information collection terminal device 3 cumulatively adds the start number and the number of special prizes each time it receives the start signal and special prize signal from the gaming machine 4a, and stores the special prize occurrence history. Then, by calculating the number of special prizes per predetermined start number of the variable display game, that is, the frequency of occurrence of special prizes, an abnormality can be determined at each start of the variable display game without waiting for accumulation of a huge amount of game information. Abnormalities can be detected quickly during operation of 4a.

  FIG. 16 is an explanatory diagram of the game history storage area according to the first embodiment of this invention, and is used as a special prize sparse state storage area and a special prize dense state storage area. This storage area is configured by a ring buffer provided in the RAM 305 of the information collection terminal device 3.

  The game history storage area shown in FIG. 16 can store the results of the variable display game executed by the gaming machine 4a in the storage area of 0 to N / p. N is an arbitrary integer, and a storage area (for example, a special prize) that sufficiently exceeds the maximum number among the start numbers of the variable display game set as the monitoring target period in FIG. 13 (B) or FIG. 13 (D). Any number of storage areas obtained by multiplying the reciprocal of the occurrence probability p by N = 5) may be used.

  The pointer indicates an area i for storing the result of the fluctuation display game currently written (outlier value “0” or hit value “1”), and the game history storage area (0) → game history storage area (1) → ... → A game history storage area (N / p) → A game history storage area (0) is used in a circulating manner.

  At this time, when the monitoring enhancement coefficient is set to “weak” with reference to the pointer, the number of past storage areas corresponding to each monitoring target period set in FIG. It becomes a storage area and a special prize dense state storage area. When the monitoring enhancement coefficient is set to “strong”, the number of past storage areas corresponding to each monitoring target period set in FIG. 13D includes the special sparse state storage area and the special prize dense state. It becomes a storage area.

  The number of special prize occurrences in the past number of executions of the variable display game in each storage area (during each monitoring target period), that is, the special prize occurrence frequency is the sum of the hit value “1” written in the target storage area Can be easily taken out.

  The game history stored in the game history storage area is continuously monitored by recording the game history continuously from the game history of the previous business day, and illegal activities across business days are monitored. To do. In addition, dummy data may be set in advance when there is no game history accumulation for the first time. The dummy data is, for example, data in which a deviation value “0” is written in a number of storage areas corresponding to the reciprocal of the special prize occurrence probability p, and one storage area is overwritten with the value “1”. Further, for example, data may be obtained by randomly overwriting a plurality of outlier values “0” with a value “1” in accordance with the occurrence probability. When random data is dummy data, the number of hit values “1” is set in consideration of the risk of being determined to be abnormal by the dummy data.

  In this way, by dividing the number of regions corresponding to the number of executions of the predetermined variable display game and storing the result of the variable display game, the execution result of the variable display game in the past predetermined monitoring period is used as the game history. Can record.

  FIG. 17 is a flowchart of the special prize dense state monitoring process, the special prize dense state reception process, and the special prize dense state release acceptance process according to the first embodiment of this invention, and the special prize is received by the CPU 101 of the game hall internal management device 1. The dense state reception process and the special prize dense state release acceptance process are executed, and the special prize state monitoring process is executed by the application CPU 303 of the information collection terminal device 3.

  When the game is started by the player, the information collecting terminal device 3 determines whether or not the special prize dense state of the gaming machine 4a is detected by the special prize dense state detection process shown in FIG. 18 (S91).

  When the special prize dense state is detected based on the determination value, the information collecting terminal device 3 notifies the game hall internal management device 1 via the network communication port 308 that the corresponding gaming machine 4a is in the special prize dense state. (S92).

  When the game hall internal management device 1 receives a notice of the special prize state of the gaming machine 4a from the information collection terminal device 3 via the network communication port 106, the game hall internal management device 1 performs a special prize state reception process (S93, S94).

  Specifically, a special prize state flag is set to the gaming machine 4a that has been notified of the special prize state (S93). Then, the output device 109 notifies that the gaming machine 4a is engaged in a suspicion that there is a suspicion that causes damage to the game arcade (S94). As a notification method, an abnormality of the target gaming machine 4a is displayed on a display provided as the output device 109, or notified by a speaker. Further, the detected abnormality may be stored as a history in the HDD 105 of the game hall management device 1.

  On the other hand, when the special prize dense state is not detected in step S91, the game hall internal management device 1 is not notified (S92), and the process proceeds to step S95.

  In step S95, when the special prize dense state is released, the fact is notified to the game hall internal management device 1 via the network communication port 308.

  When the game hall internal management device 1 receives the notification of the release of the special prize state flag of the gaming machine 4a from the information collection terminal device 3 via the network communication port 106, the game hall internal management device 1 performs a special prize state release acceptance process (S96, S97). Do.

  Specifically, the special prize dense state flag of the gaming machine 4a that has been notified to release the special prize dense state flag is released (S96). Then, the alarm that has been notified by the output device 109 during the setting of the special prize dense state flag is canceled (S97).

  FIG. 18 is a flowchart illustrating the special prize dense state detection processing according to the first embodiment of this invention. The special prize dense state detection process is executed by the application CPU 303 of the information collecting terminal device 3 every time a special prize signal is detected from the gaming machine 4a.

  First, the information collecting terminal device 3 determines whether or not a special gaming state has occurred in the gaming machine 4a depending on whether or not a special prize signal is detected from the gaming machine 4a (S101). When the occurrence of the special gaming state of the gaming machine 4a is not detected, the special prize dense state detection process is terminated.

  On the other hand, when the occurrence of the special gaming state of the gaming machine 4a is detected, the winning value “1” is written into the gaming history storage area in step S78 of FIG. In step S102, with reference to this, the special prize dense state storage area (in FIG. 16, with the pointer as a reference, the special prize dense state monitoring target period set in the determination value tables of FIGS. 13B and 13D) The number of hit values “1” written in the number of areas corresponding to (1) is counted (S102).

  Then, the determination value of the special prize dense state is read (S103), and the total of the winning value “1” (number of special prize occurrences) is compared with the determination value (S104). When the number of occurrences of the special prize is equal to or greater than the determination value, the special prize occurrence frequency is excessive, and the gaming machine 4a can be determined to be in the special prize dense state. Therefore, the special prize dense state flag is set in the gaming machine 4a ( S105).

  On the other hand, when the number of occurrences of the special prize is less than the determination value, it is determined that the gaming machine 4a is not in the special prize dense state. In addition, when the special prize state flag is already set for the gaming machine 4a, the special prize state flag is canceled (S106).

  In this way, the information collecting terminal device 3 calculates the number of special prizes per predetermined start number of the variable display game, that is, the special occurrence frequency, thereby generating a special gaming state without waiting for a huge amount of game information to be accumulated. An abnormality can be determined every time, and an abnormality can be detected quickly while the gaming machine 4a is in operation.

  As described above, in the first embodiment, the abnormality determination standard is determined in consideration of the situation of the game hall such as the monitoring resource amount, the monitoring reinforcement coefficient, and the number of operating the gaming machines 4a, Since the abnormality detection amount is adjusted to such an extent that it can be dealt with, the detected abnormality is not neglected, and the safety of the entire amusement hall is improved by accurately detecting fraud. Further, by changing the threshold value used for abnormality determination, it becomes difficult for an illegal person to grasp the threshold value quantitatively, and it becomes difficult to stop the illegal action immediately before it is determined to be abnormal.

  In addition, the amount of monitoring resources is set in conjunction with the number of employees who can perform monitoring work, and abnormality determination criteria are determined corresponding to the amount of monitoring resources. It is possible to prevent the detected amount from deviating.

  In addition, since the threshold used for abnormality determination is changed in conjunction with the number of operating machines 4a, the number of employees who can perform monitoring work and the amount of abnormality detected to the extent that the employee can deal with deviate. Can be prevented.

  Next, a second embodiment of the present invention will be described.

  In the second embodiment, since only the configuration of the monitoring resource table is different from the first embodiment described above, only the configuration different from the first embodiment described above will be described, and the same as the first embodiment. The description of the configuration of is omitted.

  FIG. 19 is a configuration diagram of the monitoring resource table according to the second embodiment of this invention, and is recorded in the RAM 103 of the remote control key management device 5.

  FIG. 19A shows the configuration of the monitoring resource table.

  In the monitoring resource table, the usage status of an apparatus (for example, a remote control key) carried by an employee in charge of floor work is managed. The remote control key is a key for locking or releasing the main body frame in which the cover glass and the game board are provided on the front surface of the gaming machine 4a. The remote control key is carried by an employee in charge of floor work when performing work in the hall of the amusement hall.

  NO indicates a number assigned to identify each device. The status indicates the usage status of the device. These devices can be used by registering an employee code at the time of use, and it is possible to determine which employee is using which device. In this case, “ON” is recorded in the status column. On the other hand, when the employee finishes the work and ends (returns) the activation of the portable device, it can be determined that the device is not being used. In this case, “OFF” is recorded in the status column. The employee code is a number assigned to identify an individual employee, and here indicates the number of the employee carrying each device.

  An income may be used as the portable device. The income is a wireless communication device and can transmit commands and information to each department in the game arcade. In this case, the use status of the income is managed by the income management device 6. The monitoring resource table is recorded in the RAM 103 of the income management apparatus 6.

  The portable device is not limited to the remote control key or the income, but may be any device that can grasp the number of employees who can monitor the abnormality in the hall of the game hall.

  As described above, the number of employees who can perform the monitoring work can be grasped by carrying the apparatus that can check the use state to the employee in charge of the floor work. In addition, by managing the usage status of each portable device in the monitoring resource table, it is possible to monitor the game in the gaming machine 4a, that is, an employee in charge of floor work who is working in the hall of the game hall. Know the number of employees you can do.

  FIG. 19B shows the configuration of the number of employees as monitoring resources.

  When the usage status of each portable device is recorded in the monitoring resource table, the number of devices in use and the number of devices not in use can be acquired. The number of devices in use indicates the number of employees who are in charge of floor work and can monitor the game of the gaming machine 4a in the hall of the game hall. Therefore, the game hall internal management device 1 can acquire the number of employees who can monitor the game of the gaming machine 4a as the monitoring resource amount from the remote control key management device 5 or the income management device 6. And the game hall internal management apparatus 1 performs the determination reference | standard setting process shown in FIG. 10 based on the monitoring resource amount acquired in this way.

  As described above, in the second embodiment, the amount of monitoring resources is set in conjunction with the number of employees who can perform monitoring work, so the number of employees and the amount of abnormality detected that the employee can handle Can be prevented from deviating.

  Next, a third embodiment of the present invention will be described.

  In the third embodiment, since only the game information collection process and the game information response process are different from the first embodiment described above, only the configuration different from the first embodiment described above will be described. The description of the same configuration as that in FIG.

  FIG. 20 is a flowchart of the game information collection process and game information response process according to the third embodiment of the present invention, in which the game information collection process is executed by the CPU 101 of the game hall internal management device 1, and the information collection terminal device The game information response process is executed by the third application CPU 303.

  First, the game hall internal management device 1 polls the information collecting terminal device 3 at a predetermined timing (for example, every 5 minutes) and requests game information of each gaming machine 4a (S111).

  When the information management device 3 receives the request from the game hall internal management device 1, the accumulated value of the game information collected from each gaming machine 4 a connected to the information management device 3 is transmitted via the network communication port 308. The game hall internal management device 1 is notified (S112). Then, the game hall internal management device 1 records the notified cumulative value of the game information in the RAM 103 (S113).

  In addition, the information collection terminal device 3 notifies the member management device 7 of the member information of each player collected from the information disclosure terminal 4e together with the accumulated value of the game information, and authenticates the member information. The device 1 is notified whether or not the player is a member (S114).

  Member information is identification information for identifying each member, and is stored in a member card possessed by a player who is a member. The membership card stores at least a membership number (ID) that identifies the membership as membership information.

  The membership card as the membership information storage medium is issued by the game hall to the player, and is composed of a magnetic card or an IC card. When a player inserts a membership card into the card insertion section 41 of the information disclosure terminal 4e or brings a membership card close to the IC card reading section, the player is recognized and attached to the information disclosure terminal 4e. Read. Then, the information disclosure terminal 4e notifies the information collection terminal device 3 of the member information. The information collection terminal device 3 notifies the member management device 7 of the member information. Note that each member may be specified using a mobile terminal owned by the player or the player's own biometric information instead of the magnetic card or the IC card.

  The member management device 7 that has received each player's member information (member ID) from the information collecting terminal device 3 collates the member information with previously stored member data, and if these data match, It is determined that the player is a member of the playground.

  At this time, even if the player is registered as a member, a member satisfying a predetermined condition is regarded as a regular member. As the predetermined condition, for example, a player determined as a so-called regular customer based on the number of visits to the game hall and past game results is set as a condition. Also, depending on whether or not the direct mail sent from the amusement hall to the member is correctly delivered to each member, the credibility of the registered content declared by the player may be determined, and the determination result may be set as a condition. . As a criterion for determining the credibility of registered contents, for example, when there is a member who cannot deliver a direct mail because the destination is unknown, the declaration contents of the member can be regarded as not credible. Such members are treated as non-members.

  Then, from the member management device 7 to the game hall internal management device 1, the determination result as to whether or not the player corresponding to the member number received from the information collection terminal device 3 is a member is a gaming machine that the player plays. It is notified together with the machine number of 4a. The game hall internal management device 1 records the notified information in the RAM 103 (S115).

  Further, the information collecting terminal device 3 notifies the game hall internal management device 1 of the operation information of each gaming machine 4a (S116). Then, the game hall internal management device 1 records the operation information notified from the information collection terminal device 3 in the RAM 103 (S117).

  Next, the game hall internal management device 1 determines whether or not the accumulated value of game information, member information, and operation information regarding all the gaming machines 4a installed in the game hall have been collected (S118). When there is a gaming machine 4a from which these information is not collected, the process returns to step S111 and the game information collecting process is continued.

  On the other hand, when the accumulated value of game information, member information, and operation information for all the gaming machines 4a are collected, the game hall internal management device 1 accumulates the accumulated value of game information for each island and the game information of the entire game hall. The values are totaled (S119). Specifically, the number of special prizes generated in the gaming machines 4a for each island or the entire game hall, the cumulative value of the number of starts, or the number of occurrences of a special gaming state during the execution of the variable display game a predetermined number of times That is, the special prize occurrence frequency is calculated.

  Next, the game hall internal management device 1 aggregates the operation information for each member based on the collected member information and operation information (S120). Specifically, based on the operation information notified from the information collection terminal device 3, the number of operating gaming machines 4a is calculated, and among the operating gaming machines 4a, members of the game hall The number of gaming machines 4a in which non-players are playing games is calculated as the number of operations. By counting the member-specific operation information, for example, the number of operations (for example, 250) is calculated by the total number of operating gaming machines 4a, and the total of operating gaming machines 4a and non-operating gaming machines 4a. The total number of gaming machines (for example, 400) in the entire game hall is calculated by subtracting the total number of gaming machines 4a in which games are played by the gaming hall members from the number of running games (for example, 100 machines). ) Is calculated. In this case, the total sum (number of members operating) of the gaming machines 4a in which the game is played by the members is 150.

  Next, the game hall internal management device 1 performs a determination criterion setting process shown in FIG. 10 based on the calculated number of operations (S121). At that time, the non-member operation number calculated in step S120 and the member operation number are weighted differently, and the total of these is used as the operation number. As a weighting method, for example, the number of operations by a member should not be added as the number of operations because it is extremely unlikely that fraudulent acts will occur. Different weights may be used depending on the player and the player whose identity is not clear, or different weights may be added depending on the amount of privilege points added for each visit and the length of the membership period.

  Then, the game hall internal management device 1 notifies the information collection terminal device 3 of the determination value calculated based on the determination criterion set in this way (S122, step S47 in FIG. 12).

  As described above, in the third embodiment, by considering the player's member information when calculating the number of operations, the number of reliable operations that are very unlikely to be performed, This eliminates the impact of mixed unreliable operations that can occur, so even under adverse conditions such as an increase in the number of operations and fewer employees capable of performing monitoring work, Anomalies can be monitored.

  Next, a fourth embodiment of the present invention will be described.

  In the fourth embodiment, since only the monitoring method by the monitoring camera 10 is different from the first embodiment described above, only the configuration different from the first embodiment will be described, and the first embodiment will be described. The description of the same configuration is omitted.

  FIG. 21 is a flowchart of monitoring camera control rule change processing according to the fourth embodiment of this invention, which is executed by the CPU 101 of the game hall internal management device 1.

  First, the game hall internal management device 1 determines whether or not the monitoring reinforcement coefficient for abnormality determination is set to “strong” (S131). The monitoring reinforcement coefficient is set by the setting input device 110 provided in the game hall internal management device 1 and stored in the RAM 103.

  When the monitoring enhancement coefficient is set to “strong”, the control rule of the monitoring camera 10 is set to setting A shown in FIG. 22 (S132).

  The monitoring camera 10 can change the shooting direction, and performs a wide range of monitoring by switching a plurality of shooting ranges (shooting directions) every predetermined time. Further, the photographing magnification can be changed, and the photographing range is switched by zooming up or zooming back as necessary. Further, when an abnormality of the gaming machine 4a is notified or the glass frame is opened, the gaming machine is replaced with a normal monitoring for a predetermined time or until the abnormality notification is finished and the glass frame is closed. Zoom in on 4a and shoot.

  In the setting A, the shooting magnification of the monitoring camera 10 is set low (the shooting range is wide angle), and the scan speed is set low. Note that the scan speed refers to a switching speed to the next screen within the monitoring range, that is, a shooting time in a specific shooting range. When the control rule is setting A, the monitoring camera 10 can simultaneously monitor a wide range of space, and can monitor from the whole. In addition, since the scanning speed is slow, the continuous shooting time within one shooting range is long.

  When the monitoring enhancement coefficient is set to “weak”, the control rule of the monitoring camera 10 is set to the setting B shown in FIG. 22 (S133).

  In the setting B, the shooting magnification of the monitoring camera 10 is set high (the shooting range is narrow), and the scanning speed is set high. Therefore, when the control rule is setting B, the monitoring camera 10 can monitor a specific narrow range in detail, and can easily specify a person as a subject. On the other hand, since the scanning speed is fast, the continuous shooting time within one shooting range is short.

  When the monitoring reinforcement coefficient is “strong”, whether the control rule of the monitoring camera 10 is set to A or B may be changed according to the monitoring policy of the game hall. Further, the setting items of the control rule are not limited to these items, and for example, an item for setting an increase / decrease in the number of activated monitoring cameras 10 may be added. Further, for example, an item for switching the monitoring camera 10 that monitors the money changer and the counter to the monitoring of the gaming machine 4a when the money changer and the counter are not operating may be added.

  In this way, by changing the control rule of the monitoring camera 10 in accordance with the set monitoring enhancement coefficient, the work of employees whose monitoring work has increased due to an increase in the amount of abnormal notification due to the stricter threshold is monitored. Can be aided by camera monitoring.

  Note that the determination of the abnormality and the operating state of each gaming machine 4a may be performed by other devices connected to the internal network such as the game hall internal management device 1 instead of the information collection terminal device 3. In this case, the information collection terminal device 3 transmits game information (or its accumulated value) detected from the gaming machine 4a and peripheral devices provided in each gaming machine 4a to the game hall internal management device 1. The game hall internal management device 1 detects an abnormality of each gaming machine 4a or determines an operating state based on the received game information (or its accumulated value). That is, the gaming machine management device described in the claims includes the information collection terminal device 3, the game hall internal management device 1 and other management devices 5 to 8, and other devices connected to the internal network. You may be comprised with either of several apparatuses. Of these, a plurality of devices may constitute a gaming machine management device, or a single device may constitute a gaming machine management device.
